Well, for a more positive comment (since everything seems to be negative - and nobody brought that up) the site is very fast. In fact pretty much everything changes instantly when i click on stuff, which is very rare. The only exception seems to be when looking at some files with a long history (not sure why the history needs to be displayed by default though).

That said, from a UX perspective, personally i prefer Forgejo - which isn't that much slower either (judging from Codeberg, it isn't instant but it is fast enough to feel "fast").
